I think that's what it would take. Or Miller/Wacha + Rosenthal/Jenkins/Martinez.

I've got to admit, I don't see what Cardinals fans see regarding Joe Kelly. I see a league average starter/replacement-level starter (OK No. 4/5 guy). A valuable commodity, to be sure, but not a star by any means. And the 7th or 8th best young and controlled option the Cardinals have in the next few years.

Then it will never happen. The Cardinals FO knows that the fan base would be so pissed off about the deal. The FO needs those 3 million fans every year to break even financially.
